Does any pleasure come without cost?
Sex - think of the risks.
Boozing - prolonged poisoning.
Admiring beauty - flirting with envy.
Learning - filling in an admitted hole.
Passing on skills - showing off.
Creating music - enduring the errors.
Reading - sensing muscles melt.
Watching movies - produced to make money.
Listening to music - the frustration of the inexplicable.
Travel - re-creating that which one's escaping from.
Doing good works - while questioning one's motives.
DIY - a botch that denies others employment.
Sport - the pretence that futile action is important.
Writing poetry - whispering inaudibly to the deaf.
Speaking a foreign language - mostly getting it wrong.
Parenthood - "Sharper than a serpent's tooth..."
I wonder about intentionally wasting time, ie, playing Solitaire. I see it as entering a tranquil state which neither harms me nor anyone else. After all, I'm pretty sure the alternative, in my case, is not improving the world. I may even be marginally more attractive playing Solitaire and thus not talking. But my unproductivity may irritate those who are forced to work.
Preferring to eat imaginative food. A pretty specialised preference. OK provided one doesn't talk about it; even more so, not proselytise.
Science is a great pleasure but possibly because it separates me from the "eng. lit. only" brigade. I can't decide whether being above average height pleases me; perhaps it might if it became: "Not being small".
Sleeping? A nothingness. Can defeatism be OK?
